December 15, 2009 - In October, Nokia filed suit against Apple, alleging that the iPhone makes use of Nokia's GSM/UTMS patents - ten patents that relate to 2G and 3G wireless connections, as well as WiFi used in mobile phones.
Now Apple has filed a countersuit. In the complaint, Nokia is sharply accused of infringing thirteen patents and "playing copycat": "Nokia has demonstrated its willingness to copy Apple's iPhone ideas as well as Apple's basic computing technologies, all while demanding Apple pay for access to Nokia's purported standards essential patent."
Furthermore, Apple claims that the ten Nokia patents in the original suit are not actually essential to GSM/UTMS, that those patents aren't infringed, and what's more, they're invalid and/or unenforceable anyway.
Interestingly, Nokia's patent infringement lawsuit is mostly concerned with the licensing terms the company feels Apple owes, and not so much about actual patent infringement or gaining a permanent injunction against Apple.
